Definitely. If you're doing coast down testing I wonder if you'd be up for a little experiment. I don't own a sedan so I can't do it
Search the forum for "coventry papers" and read about the "base plates". I was wondering if one could make something like that that goes vertically up from the edge of the trunk, like a Bonneville spoiler that goes up (instead of out) to meet the template. Does that make sense? The advantage would be if it were made out of plexi it would barely be visible.
I just thought if you're doing it maybe you'd be down. A suggestion
